VALVE.

To all whom t may concern.-

Be it known that I, HENRY E. STREIBER, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Valves, of which thefollowing is a .specication rllhe invention relates to a valve forcontrolling'the flow of gas to a plurality of burners, as for instance,a cluster of lamps` upon a post for street illumination. One lamp ofsuch a cluster is usually located on the top of a post, and theremainder of the lamps are frequently located on the ends of armsextending radially from the post below its upper end. p

lVhen a full illumination is-desired during the forepart of the night,it is customary to burn all of the lamps at the same time; but when onlya partial illumination is necessary` after midnight, it is desirable toeX- tinguish all the lateral lamps of the cluster, leaving burning onlythe one atthe top of the post; and finally at daybreak, for the purposeof economy, it is necessary to extinguish the remaining top burner, sothat until evening the supply of gas will be shut off from all thelamps. It will be understood that a pilot light is constantly burningfor each lamp, so that the same will be automatically ignited when thevalve controlling the` supply of gas thereto is opened.

The object ofthe present invention is to provide a three-position valve,by means of which the attendant can control the supply of gasto theseveral burners, at the three stated periods and for the purposeindicated, by the mere manipulation of a handle or lever suitablypositioned on the post. This object is attained by providing a valvecase withtwo ports on one side, both communicating with the gas supplypipe, and two ports on the opposite side, leadingrespectively to thesingle lamp a-nd to the lateral lamps; and by providing a hollow valvein the case, with a pluralityof ports arranged with reference to thecase ports, so that in each of the three delined positions of rotation,gas will be supplied first, to all the burners; or second, to the singleburner only; or third, will be shut off from Vall the burners.

The invention also includes certain mecha-` nism by which the valve isoperated, whereby the saine can be readily manipulated by Specificationof Letters Patent.

an attendant to set the valve in-one of its three specific positions.

preferred embodiment of the invention is illustrated in the accompanyingdrawing, forming part hereof, in which- Figure l is a perspective viewof a cluster of three lamps on a post, showing the general arrangementof the same; Fig. 2, a fragmentary section of the same, showing thearrangement of the valve and gas pipes within the post and the lateralarms thereof, the valve being turned for supplying gas to all the lamps;Fig. 3, a perspective view of the valve and adjacent parts, showing thevalve case in section, the parts being positioned as in Fig. 2, forsupplying gas to all the lamps; Fig. t, a sectional view of the valveand its case with the connected pipes, showing the valve rotated to theposition fousupplying gas to one lamp only; Fig. 5, a similar sectionalview showing the valve rotated to the position for stopping the flow o fgas to all the burners; Fig. 6, a perspective view showing details ofthe operating crank arm; and Fig. 7, a sectional view of the same.

Similar numerals refer to similar parts throughout the drawings.

The gas supply pipe l rises centrally in the post 2, which post has thesingle lamp 3 mounted on the top and two or more lamps 4 depending froma like number of lateral arms 5 extending radially from the upper end ofthe post below the top lamp 3.

The lower end of the valve case 6, is secured on the upper `end of thegas supply pipe l, and in the upper end of the valve case, is securedthe nipple 7, to which is secured the cross fitting 8, in the lateralbranches of which are 'secured the lateral pipes 9, leading to thelateral lamps 4 of the cluster. ln the upper end of the valve case 6, isalso secured the lower end of the top lamp pipe l0, which extends upwardfreely, through the nipple 7, andthe cross fitting 8, to the single lampat the top of the post; a suitable packing 8a, being' provided in theupper branch of the fitting around the pipe 10to close and seal theannular opening between them.

The body of the valve case is cylindric, or preferably slightly conica-lin shape as shown, and forms the conical seat 11 for the similarlyshaped valve 12; which valve is rotatable in the case on a transverseaXis thereof, and may be retained therein by means of the washer 13, thebolt 14, and the nut 15, or like means.

In the lower side of the case, are provided the two ports 16 and 16, oneof which ports 16, is centrally located in the vertical axis of thecase, corresponding to the axial alinement of the gas supply pipe 1,below, and

the single gas pipe 10 above; and the other Y of which ports 16, islocated at a lateral interval from the central port, in the verticalplane passing through ltheaxis of the valve as shown in the severalsections. Both or' these ports communicate with the gas supply pipe 1,as by means o1' the intervening cham-Y ber 17 formed in the lower end ofthe valve case.

Inl the yupper side of the case, are provided the two ports 18 and 18a,one of which ports 18, is centrally located in the vertical axis of thecase, and communicates directly andfsolely with the top lamp pipe 1()above; and the other one of which ports 18a, is lo cated at a lateralinterval from the central port, in the vertical plane passing throughthe axis of the valve, and communicates with the nipple 7, leadingthrough the tting 8 to thelateral lamp pipes 9. Theport 1 6a isdeflected and enlarged in the upper end of the case to surround the pipe10, leading to the top lamp.

The conical valve 12 is provided with the central hollow or cavity 19,and in the lower side ofthe valve, when the same is rotated to theposition shown in Figs. 2 and 3, the single port 20 is provided, whichregisters with the port 16a of the case; whilein the upper side of thevalve, when rotated to the same position, are provided the two ports 21and 21a, registering respectively with the ports 18 and 18a relation ofthe parts, gas is free to How from the gas supply pipe, through ports 2Oand 16a, thence through the hollow of the valve and the ports 21 and 18to the top lamp pipe 10, and also through the ports 21 and 18*u to thelateral lamp pipes 9. When thev valve is rotated one-third turn, (inthedirection of the arrow as shown in Fig. 3), to the position shown inFig. 4, the single port 22 is provided in the lower side and the singlelport 23 is provided in the upper side of the valve; which portsregister with the ports 16 and 18 of the case, and aord directcommunication, through the hollow of the valve, from the gas supplypipe1, to the single lamp pipe 10; at which time the port 18L leading to thelateral lamps, is closed.

For the purpose of continuing the supply of gasto the top burner, whilethe valve is being rotated the one-third turn from the first to thesecond position described above, the annular groove 24: is providedinthe periphery of the valve from the port 21 to the port 23 therein; anda corresponding Vannuof the case; so that in this Vlar groove 25, isprovided in the periphery of the valve from the port20 to aV point Yabout one-third of the way around,the

valve; so that a suflicient amount of gas will continue to flow throughthese grooves to supply the single lamp until the valve is rotated intothe position shown in Fig. 4, for supplying the same directly throughthe ports 16, 22, 23 and-18. By a further rotation of the valve byone-third of a` complete turn, to the position shown in Fig. 5, all theports in the case are completely closed, so

that the flow of gas from theY supply pipe is stopped, until the valveis again rotated a inal one-third turn to the position shown in Figs. 2and 3, whereupon all the lamps will be supplied as described above.

For conveniently rotating the burner into its three positions thusdescribed, the axial stem 26 is extended from the. valve, n the end ofwhich stem is secured the cam ratchet 27 provided with three equidistantstops 28 on its periphery. The crank arm 29 is pivoted on the valve stemby means of theV ears extending along the sides of the camV ratchet; andthe spring detent 30 is provided in the crank arm which is adapted tosuccessively engage the three ratchet stops."Y

The wire spring 3 1 is loosely coiled around the'end'of the `valve stemand has one. end secured to theadjacentlateral arm 5 of the post, whilethe other end is connected with the crank arm. These parts are soarranged that the energy of the wire spring serves to normally hold thecrank arm upward against theA adjacent arm of the post, Vin whichrelation of the parts, thedetent in the crank `is just above one of thestops or shoulders of the cam ratchet.

When it is desired to rotate the valve onethird turn, the crank arm isrotated to a position extending directly downward from the valve stemand upon being released is returned upward into normal position by theenergy of the wire spring. The crank arm is preferably provided with thehook 32 which may be engaged by a similar hook on the end of a rodcarried by an attendant, and the downward rotation of the arm serves torotatel the valve by the engagement of the detentwith one of the ratchetshoulders; the arrangement of the parts being such as to bring the valveinto one of its three positions, when the crank arm extends directlydownward from the valve stem,"

and 22 in the valve, but it is preferable to s ace these ports alongithevalve laterally of tie case, so as to prevent a leakage -or interferencefrom one to the other.
